dc.description.abstractAlthough many catalysts of NO reduction have been developed, the presence of excess O-2 and SO2 significantly inhibits their performance when they are used to treat the incineration flue gas. To solve such problem, this study prepared new Rh/Al2O3 catalysts and investigated the effects of Na modification, SO2 and different reductants. Experimental results indicated that the average removal efficiency of NO at such high O-2 concentrations exceeded 80% when the Rh/Al2O3 catalysts were used. CO was a better reductant than C3H6 and the best concentration ratio of reductant/NO was equal to 1. Adding Na to modify Rh/Al2O3 catalysts significantly enhanced the removal efficiency of NO from 80 to 99% at 250-300 degrees C, especially at relative high SO2 concentrations. Unfortunately, Rh-Na/Al2O3 catalysts do not have long-time activities for NO reduction, possibly because of the formation of NaNO3. Both Rh/Al2O3 and Rh-Na/Al2O3 catalysts have good performance for NO reduction, they can feasibly be used to reduce NO in the flue gas from waste incineration. (C) 2007 Elsevier B.V.
